As in, farm the machine until the gun you want is for sale, then bring in another character via split screen. Buy the gun, give it to player 2, pause the game and have player 2 quit (it'll save player 2's data, but not player 1's), quit to the PS menu (hold the PS button, then select quit game). The Torgue slots can be abused if you have a four person party, winning back torgue tokens is programed the same as Eridium, and thus everyone will get it. That means you can spend 5, and then win 3.4- the only problem being that 75% of your winnings will go to your allies and thus they have to switch off with you.
The slot machine is a new addition to Borderlands 2, and it allows you to spend all of your hard earned cash for the chance to win fantastic prizes.
The amount of money it costs to tug the one-armed bandit varies depending on your character’s level—as do the weapon rewards.
Eridium, character skins and cash are dispensed through the front tray, while weapons are acquired through the side tray on the left.
You can find two slot machines in Mad Moxxi’s bar for double the fun. You’ll also come across them in the wilderness, occasionally hoisted by a rare enemy called the One Armed Bandit.
A handy tip: Play the slots with a group of other players to multiply your cash and Eridium rewards.
Another handy tip: While your friends are doing their shopping in Sanctuary, just head on to Moxxi’s bar and gamble while you wait. Money has little use apart from buying ammunition and rare items from stores and you’ll always find more cash to buy ammo should you ever run out.
The odds may always be in the house's favor, but it's not like you've anything else to do with your money.
